ruby19: segfault while linking miniruby/generating encdb.h during build

[jowens@…]

First time I've ever installed Ruby. I can't think that this is failing for everyone, yet I'm not understanding what is different about my installation ...

Build log

[jowens@…]

$ gcc --version
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)

[jowens@…]

Workaround: install XCode 4.3.2 command-line tools, port install ruby19 configure.compiler=gcc-4.2

This appears to work. What's weird is that the portfile says "# ruby built with llvm-gcc will be broken." as does ​http://svn.ruby-lang.org/repos/ruby/tags/v1_9_3_0/NEWS . I guess my default compiler is an LLVM one. Not sure what others' is.

I cannot reproduce the error on my Lion Mac. Show me the version of your `clang' and Xcode.

% /usr/bin/clang --version
Apple clang version 3.1 (tags/Apple/clang-318.0.58) (based on LLVM 3.1svn)
Target: x86_64-apple-darwin11.3.0
Thread model: posix
% xcodebuild -version
Xcode 4.3.2
Build version 4E2002
% xcode-select -print-path
/Applications/Xcode.app/Contents/Developer

btw, configure.compiler=gcc-4.2 means using "/usr/bin/gcc-4.2", not "/usr/bin/gcc".

• gcc-4.2: non LLVM
• gcc: LLVM

successful build log

[kimuraw (kimura wataru)]

I attached main.log of my `port build ruby19'. Your log is mostly same as my log expect the errors at last.

please send me the following files to more survey.

• .CC_PRINT_OPTIONS - detail of compile options
• config.log - detail of configure

% sudo port clean ruby19
% sudo port build ruby19  # would fail
% cd `port work ruby19`
% ls -l .CC_PRINT_OPTIONS
-rw-r--r--  1 macports  admin  1364707 May  7 23:58 .CC_PRINT_OPTIONS
% cd ruby-1.9.3-p194
% ls -l config.log
-rw-r--r--  1 macports  admin  714886 May  7 23:56 config.log

[jowens@…]

So, oddly, now my compile is succeeding even after a clean. Perhaps this is because macports is caching my compiler setting? Here's the log. I am attaching the .CC_PRINT_OPTIONS and config.log. If you want to see a failed build and its settings, can you suggest how I can make macports use the default compiler?
